HUB LINER FOR RAILWAY LOCOMOTIVE WHEELS.

Application filed August 11, 1920.

or other railway wheel to prevent lateral.

play of the wheel relative to a journal boX. The invention more particularly has in mind the provision of a liner that may be appliedk to the inside of the wheel from the outer side thereof, without in any way removing the wheel, or portions of the journal box.

Ilhe invention broadly comprehends a wear plate that is welded to the vehicle hub so that the same is rigidlyv supported in position, and is not subject to displacement by vibration of the vehicle.

Alt is a further object of the invention to provide a liner whichvis inexpensive in con` struction, and may be attached to the vehicle hub without dropping the same from the locomotive or car.

ln the accompanying drawings l have disclosed the preferred embodiments of the invention, but this disclosure is merely made for the purpose of illustration, and it is apparent that the liner may be materially changed without departing from the spirit of the invention.

ln the drawings, Figure 1 is a side elevation of a locomotive driving wheel with a two part liner applied thereto.

Figure 2 is a section on the lines X-X of Figure 1.

Figure 3 is a perspective view of one section of the liner; and,

Figure 4L is a perspective view of a modilied form of the device.

Referring now more particularly to the drawings, wherein like reference characters indicate corresponding parts, the numeral 1 represents a locomotive driving wheel having the usual spokes 2, and hub 3, mounted upon an axle 4.

In the use of locomotive wheels it has been found necessary to provide a means to take up the lateral play between the side of the journal box and the wheel hub which is specification of Lettersratent. Patented Aug. 22, 1922..

caused by a wearing away of the contacting surfaces of these parts, and the present invention contemplates the provision of a removable liner adapted to be secured to the vehicle hub to compensate for this wear. The liners may of course be of the desired material and thickness depending upon the extent of the lateralplay existing between the hub and journal box. In the accompanying drawings the numerals 5 and 6 design ate sections of the liner shown in Figure 1, said liner being of a metallic formation and of the appropriate thickness. Each section has projecting therefrom integral straps 7 extending around the hub of the wheel between adjacent spokes and these straps are united to the wheel by welding. j rllhe body of the liner may also be united to the wheel hub by welding, but this is not essential as a welding` of the straps will maintain the sections in position very rigidly so that they will not be disturbed by the vibration of the locomotive.

lt will be observed that the liner is preferably composed 'oftwo sections', the ends of each section being beveled as indicated by the reference character 8, which beveled ends may be autogenously welded and there-l by maintain the twoV lsections las an integral unit. The straps 7 passing around the hub of the wheel are of course also autogenously welded. so that the entire liner is very firmly united to the vehicle hub.

In Figure i of the drawings l have disclosed a modified form of the invention, wherein the liner is composed of a single piece or yoke section of a somewhat elongated formation having the lugs 9 that are adapted to pass between vehicle spokes and are welded to the hub. With this construction as well as the construction shown in the other figures of the drawings, it will be apparent that the liner is welded to the vehicle hub from the exterior thereof, and it is therefore not necessary to drop the wheels from the locomotive or car when a wear plate is to be applied. The same may be united to the wheel without in any way dismantling the locomotive, and it will also be appreciated that by welding the wear plate in the manner indicated, no fastening screws or the like are necessary.

ln the prior art, liners have been used that are attached to the wheels by mechanical fastenings, but vibrations and stresses are so severe that these fastening devices will not hold the liners in place with sufficient rigidity. They tend to loosen or crystalline, thereby releasing fthe liner, which then drops from between the hub and its journal box. By means of the autogenous weld a fastening` of ample strength is provided, such fastening being inherently rigid and therefore cannot be accidentally displaced by vibration and stresses.

Vhile in the accompanying drawings, I have described the liner as being attached to a vehicle hub, itwill of course be understood that the'same may be Asatisfactorily secured vto the journal box without departing fromv It will also ,bey understood the inventionL` that I have merely described several preferred embodiments ,of rthe invention, and that the liner is subjectvto many changes without departing lfrom the spirit of the invention.

Having 'thus described the invention, what I claim is j l. A .liner of. the character described adapted to be interposed between a railway journal box and a wheel, said liner having cured to the-railway wheel` to maintain the liner in posi-tion.
